This is a video showing you how to remote play on any android devices. in this video I'm using the 7 inch nexus 7 (2013). this is still in development mode so give it some time if it does not work for you first attempt.

These new paid games, game trials and “buy once, play anywhere” pricing are coming to Play.

And, no, making video games with it is not the goal.

Next phase of its 'Living Games' concept involves the use of autonomous AI agents
Now that, is interesting. I'm thinking about getting me a tablet because reading on the dinky phone is not good. Not sure how well I'd be able to play remote play on a touch screen, but the idea is cool nonetheless
Edit: should just buy a vita lol
